5.6.1. Safety
WARNING
The flange and hub form a seal with the process pipework and as
such are safety critical to prevent an accidental discharge of the
process media. Keit recommends regular inspection of the
sealing components in line with local safety procedures.
CAUTION
The spectrometer and cradle assembly weighs ~32.5kg. Please
ensure adequate support.
WARNING
Pipe flanges’ permitted working pressures are temperature
dependent in accordance with the relevant standard (ANSI/ASME
B16.5 or EN 1092-1).

5.6.2. Installation
The sealing face on the probe requires a gasket to mate against the flange on the process
pipework. The gasket material must be chosen to be compatible with the pressure and
temperature range of the process media and must be chemically compatible.
WARNING
Choice of gasket material must be appropriate for the chemistry
and process being used.
The probe body and hub are manufactured from Hastelloy, which is resistant to many
aggressive chemicals; the optional ball valve is stainless steel.
You are advised to check
with Keit before installing on a new process.
